Looks good, but I do have one piece of advise for you on this and all of your future projects.
As far as the node beams go, I would suggest not putting a beam for the tie rod. Reason being that said beam will catch on certain obstacles; case in point being the Titan you made. I used the node beam from that to help make the new Bad Dawg and I noticed that the front and rear axles kept catching on the crush cars no matter what track i used, and I had a feeling that it was part of the beam structure catching. So I pressed the K key to check and I saw the beams for the tie rods, but I made sure to try and hit cars while the beam structure was still showing to confirm my theory; sure enough on the first hit, the beam for the front tie rod caught the top of the car and the rear also caught the top of the car on the way over.
I figured I'd give ya a heads up on this because this because those beams catching can cause issues for people using your trucks in events. The rest of what you did with the node beam is fine, just gotta get rid of the beams for the tie rods.
